have a magnotron from gottlieb ,got it from a guy that said it used to work well a few yrs ago then it started acting up .he called a guy off of craigslist that said he could fix it .the "repairman"told the owner he needed a new score motor,so he bought a new one for the game and had it installed the game never worked right since
i have started to go thru the switches ,score motor switches seem to be ok ,making and breaking when they should
when i reset the game with credit button
it resets player one, ball one, lights ball is ejected
can play the ball ,scoring on playfield ok
ball drains and is kicked out onto shooting lane again ,ball count ,player number doesn't change
when i hit credit to reset score reels,they dont go to zero
assuming the score motor is installed right any ideas
thanks ,

Do you have the schematic? I dont have that pin, so guessing a bit.
if you have not already done so, you will need to go through the player unit, and the coin unit. clean, lube, adjust switches.
there is a outhole relay, chk that too.

The player unit in the head must advance to change player. This will also hang up a real reset. Try pushing the plunger and manually move it when reals are trying to reset. This unit controls to which player gets points from playfield.

There is also a set of reset relays in the head. I would go thru them all and file and gap.

The outhole points must be adjusted right to advance the player unit.

ok thanks will try this and let you know what happens
just hope the score motor was installed correctly ,thats an awful lot of wires to sort and solder !

If you can post a couple pics of the score motor and its associated switch stacks, those of us who know Gottlieb EMs can help you evaluate if the motor replacement was done correctly.

This is one of those repair jobs that if you do it right, it's basically a non-event. But if you do it wrong, you can really mess up the operation of the game across the board.

The person who put in the new motor should not have needed to unsolder ANY of the motor switch wires - just the two wires going to the motor itself. We can hope that they knew what they were doing.

Here are some pictures of the score motor .the first one is the one that was taken out of the pin. All the wires had been removed thats why i was concerned about the wiring getting screwed up .although im hoping its just some switch adjustments i need to make .

Are you 100% sure that the motor in the bottom pic of post #8 is the original score motor from the Magnotron? That looks more to me like a salvage score motor assembly that was cut out of a game being parted out.

If that picture really is your original score motor, then I'm sorry to say it doesn't make any sense. There is no reason to ever do a swap that way. It strongly suggests that the person who did this was not qualified to be working on an EM.

That said, all is not lost. You can still troubleshoot and fix your game, but it will be a little more challenging. If someone really did cut all of the motor switch wires off an original motor assembly and soldered them onto a new motor assembly, then you are going to need to check the wiring for all of the motor switches on anything in the game that isn't working properly. That's because if any of the wires got soldered onto the wrong switch lugs, the sequencing logic will be messed up for whatever function was mis-wired.

Do you have a schematic for your game?

Thats what it is.and i agrree with you.im no expert but with this sites help and what ive learned i probably brought back to life close to 30 pins and have never had to replace a score motor . Anyway what i was thinking is if i concentrate on one switch stack on the score motor at a time submitting good pics and or noting the wire colors can we corroborate and confirm the wiring . I figure just from the way the wiring harness is the wire groups are probably on the right switch stack grp . It just may be the order of the wires on each stack that may be mixed up . Im am going to go tnru the other relays and player unit first in hopes that may be the fix
Thanks

since the ball count or player counts isnt working ,also score reels do not reset but a game can be played could it be the switch under the ball drain ,and where do these wires go ,do they go to a score motor switch?
thanks

ok so when i was looking at this machine last nite and trying to follow the set up sequence supplied thru the above website ,when i push the center credit button ,start relay locks in so does the v relay,i think this is the replay relay then the u relay closes to reset the relay bank ,the sb relay switch on relay bank doesnt lock ,but if i manually activate it the score reels do reset to zero
so it looks like the sb switch is activated by a motor switch 1A and 4 B and the play unit is also activated if i remember from the start sequence thru 1A also
so do i start looking at the wiring to switch 1 A and could anyone tell me the order of wires on this switch and maybe switch 4B
and as usual thanks for the help

ok looks like the switch stack for motor switch 1A may be ok ,looks like he simply took it off old relay and replaced it on second
was wondering if i posted the wire arrangment on the other switches according to color to see if someone can compare to a magnotron they have so i can see if my wiring is correct
also the v relay is activated when the game is resetting ,should this be happening
thanks

I have a Magnotron.

Tell me what you want pictures of and I will send them to you.

Might not be for a few days as I may not be home until Friday.

Turn-out the score motor was wired correctly
I cleaned up the playerror unit in the head recapped the switches and that was it .
Now I have to adjust the gate that opens at the bottom of the playfield ,mine either opens too far or not enough .
Any hints on how to adjust the gate or the wire under the playfield that opens and closes the gate

I meant regapped the switches!
